2005 Chevrolet Malibu
Two Chevy sedans with automatic transmissions are included in a top-ten list for fuel economy, with the midsize Malibu beating its Japanese and Korean rivals. Granted, you’ll have to opt for the Malibu’s smaller 2.2-liter four-cylinder engine linked to a four-speed automatic transmission, but you’ll be rewarded with 35-mpg on the highway. The Malibu offers 101 cubic feet of passenger volume. Despite a base price in the $20,000 range, this is your best bet for an efficient domestic sedan.
